pensing mechanisms, whereinliquid', as wat er, or 011, or other fluids to be d spensed are placed and s ma ntained in the heated condition While the same 'isbe'ing dispensed, provision beingmade in the dispensing mechanism for the dispensing of the heated liquid in quantities desired byinterposing of a needle valve .at the outlet through the base of the same and adapted to being manipulated by a thumb actuator adjacent the handle. sup-- f porting the same.

f i A further .ob ectconsists in an adjustable threaded member at the outlet through the base adapted to maintain a tight pint and a. removable outlet member which may be removed and replaced,,:to incr'ease or de-,

crease the diameter of the same,"it being determined by the liquid to be dispensed therethrough. I e

Our invention is particularly adapted for use in creameries, milk condensers and other placeswhere milk is being tested and wherein a device for fillingt-he' testing bottles having restricted graduated necks is required."

In the filling operations but small quantities of the filling liquid are required in the-final filling operations. With these and the invention consists in certain novel fea tures of construction and combination of parts, the essential elements of which are set forth in the appended claim and to a preferred form of embodiment of which is here.-

inafter shown with reference to the drawings which accompany and'form a part of this specification. I

In the drawings,

ated necked bottle of the type used in the testing of milk for the butter fat content.

Fig. 2 is an enlarged sectional view of our 1 device made to show the construction of the same and the" heating elements for maintaining the liquid to be dispensed, in a heated condition; during the dispensing of the same.

Fig. 3 is a front view of the threaded valve stem carrying unit, shown removed from the device. Y Like reference characters refer to like parts throughout the several views.
